IMPROVEMENT 1N INKisTANDs.

1 Specification forming part of Letters Patent No. 147,031, datedFebruary 3, 1874; application filed l April 11, 1873.

V is a top view, and Fig. 5 a transverse section, of

the ink-reservoir supporter. Fig. 6 is a top view of the seat of therotary cover. Fig. 7 is a transverse section of such seat, the sectionbeing through the bayonet-connection projections or hooks. Fig. S is anunder-side view, and Fig. 9 a transverse section, of the rotary cover.Fig. 10 is a top View of the combined ink-reservoir and well and theelastic cap of the said reservoir.

In such drawings, the ink-reservoir is shown at A, and the well at B,the two being formed, as represented, in one single piece of glass, andin a suitable mold. In the lower part of the partition or wall a,separating the well from the reservoir, there is a duct or passage, b,which, after the combined ink-well and reservoir is cast or founded andbecome cool, I make by a lever provided with a tooth or spur. I forcethe spur or pivot through the wall, which I cast sufficiently thin toenable such to be easily effected. The ink-well is conical or tapering,in manner as shown. In the lower part of the ink-well, and directlyopposite the passage b, Iform, at aright angle with the axis of the saidpassage, an abutment or anti-deector, c, the purpose of which is toprevent the ink,

` when rushing suddenly from the reservoir into the well, from beingdeflected upward and ,out of the well, as it would be were it to im-4pinge against the inclined inner surface of the Well. Such an escape ofink is very liable to take place without the anti-deector, but with suchit is entirely prevented. The combinedsupporter. An elastic cap orcover, E, made of india-rubber, and in the form as shown, ts into themouth of the ink-reservoir, and rests on the top of the same. This coveris composed of a flat dome, f, a tubular cork or extension,

i g, and a circular ilange, hf, all beingforined and arranged in manneras shown in the drawings..

In connection with the supporter C and the combined glass reservoir andwell, I employ a rotary cover, G, and a domed seat-plate, F, the latterserving as a cap for the ink-well, and being provided with an opening,h', to constitute a mouth for the said well. The dome i of the plate Fhas a curved slot, k, and a key-hole, l,

formed through it, and arranged in manner as shown, and it also haspivoted to it, and arranged so as to extend across the slot k, a tongueor depressor, H, which, when the seatplate F is in place in thesupporter C, rests directly ou the top of the elastic cover E; Thesupporter C has locking-flanges m n o arranged around within it, overthe ink-reservoir rest, such an ges having spaces p q between them.Furthermore, a spring, r, arranged with respect to their flanges inmanner as shown, is for a purpose to be hereinafter explained. Theseatplate F has three projections, s t t, extending down from it, two ofthem, t t, being hooked to operate with the flanges m o in connectingthe said seat-plate F to the supporter C. By hooking one hook, t, underthe flange m, the other may be moved down through the space q. By nextturning the seat-plate a little on the supporter C, the projection swill be moved by and beyond the spring r, which, as soon as theprojection may have passed its free end, will spring inward, so as, withthe projection s, to prevent the seat-plate from being turned in areverse direction. Thus it will be seen that the spring 1' and theprojection s, combined with' the above described bayonet connec tion 7of the seat-plate and supporter, serve to lock the seat-plate to thesupporter. By inserting a key, u, (see Fig. 11,) in the key-hole of theseat-plate and turning such key, the

spring may be forced back so as to allow the seat-plate to be turnedback far enough to admit of it being disconnected from the supporter.The rotary cover G, formed as shown, is pivoted to the seat-plate, thepivot being seen at o. Such cover is provided with a cam or inclinedprojection, w, to extend through the curved slot of the dome of theseat-plate, and against the movable tongue or depression H.

On turning the cover Gr around so as to uncover the mouth of theink-Well, the cam Will be moved so as to force downward the depressionupon .the elastic dome of the cover E. Such will press down the dome,and, as a consequence, the air underneath it and in the ink:- reservoirwill be compressed, and will force ink out of the reservoir into theWell. On moving the cap so as to cover the mouth of the ink-Well, theelastic dome of the cover E will expand, so as to cause the compressionof the air to cease and the ink in the Well to be driven back into thereservoir. Thus, by the movements of the cover, the ink may be forcedinto the ink-Well from the reservoir and be drawn back therein, so as tobe preserved from loss by evaporation during such times as the inkstandmay not be in use.

. This inkstand is designed for a school-desk, but may be lotherwiseused.

I claim as my invention the following:

1. The ink-reservoir A and the conical Well B, arranged, connected, andprovided with the anti-deiiector c, disposed in the Well, and withrespect to the communicating duct b, as set forth.

2. The combined glass ink-reservoir A and Well B, cast in one piece, andhaving their duct of communication, b, subsequently made by breakingthrough the Wall of separation of the Well and reservoir, as stated.

3. The ink-reservoir supporter C and the cover-seat F, constructed,arranged, and provided With the bayonet-eonnection, Jche locking-stud s,and spring fr, and key-hole l, all substantially as explained andrepresented.

4. The rotary cover G and its cam fw, combined and arranged with thecover-seat F and its slot 7c, and with the depressor H, pivoted to theseat, all being for use with the elastic cap E of the ink-reservoir, inmanner as described and represented.

5. The supporter C, the cover-seat F, the rotary cover G, the cam w, thedepressor H, the elastic cap E, and the ink-Well B, and reservoir A,arranged, constructed, and applied together substantially as described.

6. The ink-reservoir elastic cap E, made as described, viz., of the latdome, its circumscribing ange, and the tubular cork, arranged asspecified, whereby it is rendered applicable to an ink-reservoir, as setforth.
